Many of the weapons in the game are weapons from the Drakengard series. At the end of the first Drakengard title, Spoiler:Caim dropped his weapons above Tokyo, where they were scatted, only to be found centuries later by Nier. They were later discovered and renamed:

• Moonfire became Moonrise
• Hymir's Finger/Broken Iron became Iron Will
• Battlelust became Captain's Holy Spear
• Ravenfeeder became Rebirth
• Dragonhook became Earth Wyrm's Claw
• Twins' Fang became Fang of the Twins
• Knight's Vow became Dragoon Lance
• Maiden's Kris became Nirvana Dagger
• Foul Blade became Vile Axe
• Kingsblood became Ancient Overlord
• Takamasa became Faith
• Skald's Song became Blade of Treachery
• Writheheart became Lily-Leaf Sword
